Preparing canals by hand today is like using chisels, hoes and diamond disks to do operative. It's possible, but why would anyone do that?

Having said that, one of the most valuable skills learned at the course is initial probing, and there are a lot of older patients who have canals that are impossible to do with ANY automated technique, including this one.

Interestingly, there is no other endo course (at least that I know of) that even teaches how to work the first file through the canal to the apex i.e. initial probing. In fact we have several techniques and instruments designed specifically FOR that.
